To calculate the wavelength of the infrared radiation with a frequency of 17.3 THz, we can use the formula:
c = λν,
where c is the speed of light and ν is the frequency.
The speed of light, c, is 2.998 × 10^8 m/s.
First, let's convert the frequency from THz to Hz:
17.3 THz = 17.3 × 10^12 Hz.
Now, we can rearrange the formula to solve for the wavelength, λ:
λ = c / ν.
Substituting the values:
λ = (2.998 × 10^8 m/s) / (17.3 × 10^12 Hz).
Calculating this expression gives:
λ ≈ 1.73 × 10^-5 m.
Finally, to convert this value to picometers (pm), we multiply by 10^12:
λ ≈ 1.73 × 10^7 pm.
Therefore, the wavelength of the infrared radiation is approximately 1.73 × 10^7 pm.
Infrared radiation from young stars can pass through the heavy dust clouds surrounding them allowing astronomers here on earth to study the earliest stages of star formation before a star begins to emit visible light suppose an infrared telescope is turned to detect infrared radiation with a frequency of 17.3THZ calculate the wavelength of th infrared radiation
